A coolant system for an internal combustion engine equipped with a radiator, involving the use of a reservoir utilized in a semi-hermetically sealed relationship with the engine and radiator, such that only rarely does additional coolant liquid need be added to the coolant system. This system has the safety of a pressure cap set to release in the pressure range of between 10 and 20 pounds per square inch, but no readmission valve is utilized in the cap, thus excluding unwanted atmospheric air from the coolant system. The reservoir is preferably insulated and of elongate configuration.

Abstract:
An information processing system includes a plurality of data processing tools, an atomic information repository, and a plurality of generated translation engines. Each data processing tool processes data in accordance with an associated data model, and in the process generates access requests for accessing data in accordance with its associated data model. The atomic information repository stores data items using an organization in an atomic data model which corresponds to the combination of the data models associated with all of the tools. Each translation engine is associated with one of the tools. Each translation engine receives an access request from its associated tool in the associated tool's data model and performs a translation operation to translate the request to the repository's atomic data model, and initiates an access operation with the repository in connection with the translated access request. A system manager is provided which can, when a new tool is added to the system, update the repository's atomic data model to reflect the added tool's associated data model, generate a translation engine for the new tool, and also update the translation engines associated with the existing tools to reflect the update.
An expansion device for refrigeration systems replaces capillary tubes and automatic expansion valves. A housing is provided having an inlet tube for connection to the liquid line from the condenser and an outlet tube for connection to the evaporator. The outlet tube has a valve like seat in its inner end and orifice grooves formed in the seat. A steel ball is movably disposed in the housing such that liquid refrigerant during compressor operation forces the ball into the seat thereby forming an expansion orifice between the ball and the seat.
Engine Pressure-Vacuum Cooling System With A Horizontal Coolant Storage Tank
An engine pressure-vacuum cooling system with a horizontal coolant storage tank wherein the cooling system is pressurized during engine operation and maintained under vacuum when the engine is inoperative. After filling the system with coolant, during the initial engine warm-up cycles air is purged through a one-way valve and the cooling system thereafter sealed against further entry of air. The storage tank includes a means for confining sludge and other debris to the tank and a means for warning when the system vacuum exceeds a pre-determined level.
